The aim of this project is to address the problem of detecting liquid ingress at National Transmission System (NTS) Entry Points through the development and testing of a prototype analyser which identifies the presence of liquid by means of a video identification system.
The programe will perform a full review of each system (fixed, mobile) will be presented. If the trials prove successful, the systems will be adopted as a business as usual system for liquid monitoring within the NTS. The necessary procurement and National Grid specification/standards, inclusive of standard design templates, will be amended accordingly.
The ability to monitor contamination will allow the control of incidents of liquid contamination to be pro-active, rather than re-active.

Potential delay in the repair of damaged filters (£20k each).

Prevention of Containment incident costs ~£50k
